608 Capt. E. Y. Watson — Butterflies from Myingyan. [No. 3, 



Felder, was met with, though it is probably not uncommon ; Talicada 

 nyseus, Guerin, which as far as Burma is concerned only occurs in the 

 drier districts, was excessively common; Colonel Swinhoe has recently 

 described the Khasia Hill race of this species as distinct from the 

 typical South Indian race under the name T. hhasiana, the only point of 

 difference being that in T. khasiana the rows of white spots on the 

 underside of the forewing are more pronounced than in typical 

 T. nyseus, so that in the Burmese race one would expect these spots to be 

 still more developed. This however is far from being the case, as in 

 the Burmese specimens the spots are as a rule even smaller than in 

 typical Southern Indian ones, while in many cases the spots are almost 

 absent, the outer half of the wing being entirely black, with a few 

 faint greyish irrorations in place of spots, so that in this respect the 

 Burmese race is nearer to the Southern Indian one than to the Khasi 

 Hill one, which seems rather to suggest that the character taken by 

 Colonel Swinhoe is not specific; Burmese specimens however differ from 

 Southern Indian ones in having rather less red on the upperside of the 

 hindwing, and in the chequering of the fringe being obsolescent instead of 

 very pronounced, none of the differences however seem to warrant the 

 Burmese race receiving a separate name. No Nacaduba or Lampides 

 was observed. Gatochrysops strabo, Fabricius, with its unnamed dwarf 

 form, occurred commonly, also 0. pandava, Horsfield, with its dwarf 

 form G. contracta, Butler. I have recently been able to examine the 

 type specimen of the last-named form, and find that it is not as sug- 

 gested in " Butterflies of India, &c, " the dwarf form of G. cnejiis, 

 Fabricius, but of G. pandava, and has two seasonal races precisely 

 similar to those of the larger race ; C. cnejus, the dwarf form of which 

 has been named G. hapalina, Butler, was not met with. Attention 

 does not appear to have been previously drawn to the fact that all 

 the three common species of Gatochrysops which occur in India have 

 corresponding dwarf forms, these dwarf forms are commoner in dry 

 than in wet districts, and in arid tracts like Sind probably exceed the 

 larger race in numbers. Of other named Gatochrysops, G. theseus, 

 Swinhoe, is a " sport" of C. cnejus, and the type of 0. nicola, Swinhoe, 

 is a female of G. pandava, somewhat intermediate between the two 

 seasonal forms. Tarucus plinius, Fabricius, occurred commonly, also 

 T. callinara, Butler, the two seasonal forms of the last species differ 

 slightly in the tone of the dark markings on the underside, which in 

 the rainy-season form are almost black and in the dry-season form are 

 rusty-brown, the position, size and shape of the markings do not 

 appear to differ in the two races, nor is there any perceptible difference 

 in the shade of blue or breadth of the margins on the upperside.
